WAL L No. 796,831. Specification of Letters Patent. Patented Aug. 8, 1905.

= Application filed February 8, 1905. Serial No. 244.780.

To all whom, it may concern:

Be it known that I, JOHN ALBERT FERGU- SON, a citizen of the United States, residing in the city and county of Denver and State of Colorado, have invented certain new and useful Improvements in Walls, (Case 13,) of which the following is a specification.

My invention relates to improvements in building-blocks and walls in which the wall is built of blocks made from any suitable material.

The objects of my invention are to provide a building block of a shape which can be readily molded from any desired material and to provide a wall which canbe readily constructed and which will be durable and will be provided with air-ducts to prevent penetration of moisture.

I refer now to the drawings in further explaining the nature and objects of my invention, in which Figure 1 is a perspective view of the block used in constructing my new wall. Fig. 2 is a perspective view of a section of wall built of blocks represented in Fig. 1. Fig. 3 is a top plan view of a course of blocks as laid in the wall.

In giving a further and more detailed de scription I again refer to the block in Fig. l of the drawings, in which A represents the body portion thereof. It is provided at each end with right angled flanges a. Extending from the body portion of the block and in the same direction as the right-angled flanges at the ends are two intermediate flanges a and a The flange a is of greater length than the flange (L as illustrated. The end flanges a provide seats for the long flange a It will be readily understood by reference to Figs. 2 and 3 of the drawings that the wall is constructed of two courses of blocks with their flanges oppositely disposed, as described and shown in the drawings. The courses are laid to break joints and to provide bonds. The long flanges a rest against the end flanges 0/, preferably abutting the end flanges of two blocks, as shown in Figs. 2 and 3. The short intermediate flanges 0. being preferably of the same length on all of the blocks used in the wall engage each other centrally-that is, centrally between the inner and outer faces of the wall. In this manner the bonding is more effectively made, as the long flanges in the next courses bond over the central joints and the short intermediate flanges bond over the joints formed by the end flanges and the long flanges engaging each other.

I claim 1. Abuilding-block comprising a body portion having right-angled flanges at the ends thereof of substantially equal length and two intermediate flanges, one of greater length than the other, the said intermediate flanges being of greater length than the end flanges.

2. A building-block of the class described comprising a body portion having abutments at the ends thereof of substantially equal length on one face only, intermediate laterally-extending flanges extending from the same face on which said abutments are provided, one of said intermediate laterallyextending flanges being of greater length than the other, substantially as specified.

3. A wall composed of a plurality of blocks each block comprising a body portion having right-angled terminal flanges and intermediate laterally-extending flanges disposed in the same direction as are the terminal flanges, said blocks being laid side by side and arranged in superposed courses with the end flanges of the blocks on one side of the wall engaging the long intermediate flange of the block on the opposite side of the wall and the end of the short intermediate flanges abutting each other centrally between the inner and outer faces of the wall, substantially as specified.

4. A wall composed of a plurality of blocks each block comprising a body portion having angularly-disposed terminal abutments and two intermediate flanges one of greater length than the other, both of said intermediate flanges of greater length than the said terminal abutments, the said blocks being laid side by side and arranged iii-superposed courses with the long intermediate flange of the blocks on one side of the wall engaging the terminal abutments of two blocks on the opposite side of the wall, the ends of the short intermediate flanges engaging each other centrally, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN ALBERT FERGUSON.
